MEDICAMENT APPLICATOR Filed NOV. 15, 1949 l INVENTOR Harry D. Al/Vlnf/e,../f. A ATToR/v Y Patented Mar. 11, 1952 UNITED STATES' PATENT 7 Claims.

This invention relates to a medicament ap` plicator comprising a member removably mounted on a medicament carrying container With the container in medicament discharge communication with a drop dispensing portion of the member, and an air bulb adjustably carried by the member in air communication with the container ato exert air pressure in the container and expel medicament in predetermined quantities from the container into the drop dispensing portion.

rlfhe object oi the invention is to facilitate the administration of drops of medicament to a part of the human body, such as an eye or nose, Without Waste oi the medicament and inconvenience to the user.

Another object or the invention is to dispense the medicament in desired quantities to the eye or nose.

Other objects and advantages of the invention will be described hereinafter.

1n the drawing accompanying and forming a part of this application,

Figure 1 is a sectional view of a member forming the embodiment of the invention mounted on a medicament carrying container.

Figure 2 is a view similar to Figure 1 showing a inodication of mounting the member on a container.

Figure 3 is a perspective view of the member applied to an eye with a side wall portion broken away to show a medicament dispensing portion of the member.

The embodiment of the invention is illustrated in the accompanying drawing as particularly adapted to dispense drops of medicament to an eye and comprises an eye cup member including a side wall fl having a rounded edge conforming to the contour of the eye socket and an end Wall 5.

The end Wall 5 is provided With a tubular projection 5 extending from the inner face thereof into the eye cup member and adjacent to a portion of the side wall 4. The tubular projection is shown as integral with the end Wall 5. The bore of the tubular projection 6 is extended through the end Wall 5, as indicated at 1 in Figure 1. The end of the tubular projection 6 terminates Within the rounded edge of the side Wall l2. The tubular projection I is positioned in the eye cup member to discharge medicament adjacent to the corner portion or canthus of the eye.

The outer face oi the end Wall 5 is arranged with tWo tubes 8 and 9 integral with and extending from said end Wall in spaced relation to each other. The tube 8 extends substantially in 2 the plane of the side Wall 4 and the tube 9 is disposed in the end Wall 5 between the bore 'I and the tube 8. The bores of the tubes 8 and 9 are connected in communication with each other through a passage It! in the end Wall 5 extending in the plane of said end Wall.

The outer face of the end wall 5 is also arranged for mounting a medicament carrying container I I thereon in communication with the bore "I and tube 9.

In Figure 1, there is shown one form of mounting the container I I on the end Wall 5 comprising an annular skirt I2 extending from and integral with the outer face of the end Wall 5 and surrounding the area of said face occupied by the bore 'l and tube 9. By this arrangement of parts, the container is in medicament discharge communication with the eye cup member through the bore 'l and in air communication with the bore of tube 8 through the bore of tube 9 and the passage II). The skirt I2 is internally screw threaded to receive corresponding screw threads on the neck portion of the container and secure the eye cup member to the container, as indicated at I5 in Figure 1. To provide a liquid tight seal, a gasket I4 is engaged between the outer face of the end wall 5 Within the skirt I2 and the mouth of the container II. The gasket I4 is arranged with appropriate openings for the bore I and tube 9.

In Figure 2, there is shown another form of mounting the container II on the end Wall 5 comprising a plug I5 of resilient material, such as rubber or cork, to t into and seal the mouth of the container II. Said plug I5 is provided with a pair of parallel openings therethrough for the tube 9 and a tubular extension I5 extending from the outer face of the end wall 5 With the bore of said tubular extension I6 in axial alinement and communicating With the bore l. The end portion oi the tubular extension I6 is extended from and peened over the end of the plug I5 to retain the plug on the outer face of the` end wall 5, as shown at il in Figure 2. l

In the structures shown in Figures 1 and 2, the tube 9 is of a length to extend to the lower portion of the container II. The length of the tube 8 is shorter than the tube 9 and the tube 8 is bent to extend parallel to the container II to permit the slidable engagement of an air bulb I8 of resilient material, such as rubber, on the end of the tube 8. The slidable engagement of the bulb I8 on the tube S permits adjustment of the bulb I8 longitudinally of the tube 8 to vary the amount of air pressure delivered to the container El and the quantity of medicament discharged from the container ll through the bore 'I into the eye cup member by the compression of the bulb I8. f

When the device as shown in Figures l and 2 is not in use, the tubular projection 6 is closed by a removable closure cap I9, as shown in Figure 1.

When it is desired to use the device for dispensing drops of medicament to a nostril of a nose, the side wall 4 of the cup member is permanently removed to permit the engagement of the tubular projection 6 in said nostril.

Having thus described my invention, I claim:

1. In a medicament applicator, a member having one face arranged for the mounting of a medicament container thereon, a tubular projection on the opposite face of the member having a bore extending through said member within the mounting forv the medicament container to receive medicament from the container, a tube extending from the first face of the member Within the mounting for the medicament container to extend into said container, a second tube extending from the rst face of the member exteriorl-y of the mounting for the medicament container and communicating with the first tube through a passage in the member, and an air bulb mounted on the end of the second tube to exert pressure in the medicament container and force a predetermined quantity of medicament through the tubular projection.

2. A medicament applicator as claimed in claimV 1, wherein the tubular projection and tubes are integral' With the member.

3. A medicament applicator as claimed in claim l, wherein the air bulb is adjustably mounted the secondtube to discharge predetermined quantities of medicament through the tubular projection'.

fi. A medicament applicator as claimed in claim l, wherein the mounting for the medicament container comprises an annular' skirt integral with the member and' arranged to be secured on the neck portion of the medicament container.

5. In a iri'edica'm'en-t applicator as claimed in claim 1, a tubular extension extending from the rst face of the member and having the bore thereof communicating With the bore of the tubular projection, and the mounting for the medicament container comprising a plug of resilient material mounted on the first tube and the tubular extension and adapted to be engaged in the mouth of the medicament container with the end portion of the rst tube extending from the end of the plug and the end of the tubular extension peened over the end of the plug to secure the plug to the member.

6. A medicament applicator as claimed in claim l, wherein the tubular projection is adjacent to a side of the member, the second tube is adjacent to the opposite side of the member, and the first tube is between the tubular projection and the second tube.

7. In a medicament applicator, a member having an end Wall arranged with a bore extending therethrough and a passage in said end Wall extending in the plane thereof, tubes communicating with the opposite ends of said passage and extending from one face of the end Wall, a medicament container removably mounted on said face of the end Wall in communication with the bore and one of the tubes, and an air bulb mounted on the other tube, in communica: tion with the passage, whereby compression of the air bulb exerts pressure in the medicament container and expels medicament from the container through the bore.
